SignedX focuses on the most widely used and reliable document formats, making it easy to prepare and send envelopes without worrying about compatibility issues. The platform aims to ensure your documents upload smoothly, render clearly, and provide a seamless signing experience for your recipients.
Supported file types
SignedX currently supports the following formats:
- PDF (application/pdf)
- DOCX (application/vnd.openxmlformats-officedocument.wordprocessingml.document)

By focusing on industry-standard file types, SignedX ensures high-quality document handling, consistent formatting, and a dependable experience from upload to signature.
If you're unsure whether your file is ready to send, simply convert it to PDF or DOCX and you'll be good to go.
